Question

X + Y = 105 and X - Y = 35 . Find the value of X and Y . (with explanation pls)

Answer 1

Answer:

x=70 y=35

Step-by-step explanation:

x+y=105 (equation 1)

x-y=35(equation 2)

now,

add eq. 1 and 2

x+y+x-y=105+35

(+y and -y got cancelled)

2x=140

x=140/2

x=70

now, in eq. 1

x+y=105

y=105-x

y=105-70

y=35

Pls mark it as the brainliest

Answer 2

Answer:

x=70  y=35

Step-by-step explanation:

x+y=105  (equation 1)

x-y=35(equation 2)

now,

add eq. 1 and 2

x+y+x-y=105+35

(+y and -y got cancelled)

2x=140

x=140/2

x=70

now, in eq. 1

x+y=105

y=105-x

y=105-70

y=35
